When it comes to audio compression, WAV and MP3 are two common audio file formats that we compare. There is a new format, too, that prevents the loss of data known as 32-bit float. This format is preferred for EVP because it does not effect the low noise or distortion where an EVP could be hiding.
Types of Sound Files in Ghost Hunting
WAV is an uncompressed audio file format that is typically used in professional audio applications, including music production and sound design. Because it is uncompressed, WAV files can be very large in size and not suitable for certain applications where file size is limited. Because there is no data compression involved, however, the audio quality is not compromised. This means that the full dynamic range of the audio signal is preserved.
MP3 is a compressed audio file format that is commonly used for music distribution and playback. MP3 files are much smaller in size than WAV files, making them more convenient for streaming and downloading. However, the process of compression involves the removal of some of the audio data, which can result in a loss of audio quality. In particular, the higher the compression ratio used, the more pronounced the loss of audio quality.
It's worth noting that there are multiple levels of compression available for MP3 files. There are also now other compressed file formats, such as AAC and FLAC, that offer better sound quality than MP3 while still maintaining a relatively small file size.
In summary: WAV files are generally considered superior in audio quality, but they can be very large in size. MP3 files are much smaller in size but may sacrifice some audio quality in the process. The choice between the two formats depends on the specific needs of the application, as well as the desired balance between file size and audio quality.
Back to Ghost Hunting: 32-Bit Float Compression
32-bit float, also known as single-precision float or simply float, is a data type used to represent numerical values with decimal points in computer systems. It is commonly used in digital audio and image processing applications.
In the context of audio, 32-bit float refers to a specific format for representing audio data. Traditional audio formats, like WAV and MP3, use fixed-point data formats with a limited range of possible values. 32-bit float uses a floating-point format that allows for a much wider range of possible values, including values smaller than 1 and larger than 0.
The benefit of using 32-bit float in audio processing is that it can help prevent loss of data and distortion when manipulating audio files. This is because the wider range of possible values allows for greater precision and more accurate calculations.
Additionally, 32-bit float can help avoid clipping or distortion when working with high dynamic range audio, as it allows for values above 0 dB without distortion.
Recordings in Paranormal Investigation
32-bit float is a format used to represent numerical data in a computer system, and is particularly useful in digital audio processing due to its wide range of possible values and ability to preserve audio quality during processing.
In ghost hunting, the 32-bit float format is ideal. It has the widest range of possible values, meaning it can pick up even the hardest-to-catch EVPs (electronic voice phenomenon).
As paranormal investigators process sound files to isolate EVPs, 32-bit float files are the best format to retain quality while the file is refined, too.
